Abstract
The invention is based on the concept of providing a fuzzy inference machine having a fuzzy logic unit. The fuzzy logic unit converts an input value into a fuzzy scalar on the basis of scalar fuzzy operators. The converted fuzzy scalars are processed by means of fuzzy interconnection operators to give scalar output values. The invention is therefore based on providing the inference machine of an expert system with a fuzzy logic unit which can operate directly with scalar data values and which permits the processing of unsharp knowledge. Then neither a fuzzifier nor a defuzzifier are required. In accordance with the (unsharp) knowledge of the knowledge base, the input values are compared by (unsharp) fuzzy operators to the presettings and afford (unsharp) information in the range of from 'completely false' to 'completely true'. Also shown is an electrical therapy device having a fuzzy inference machine of that kind.
